Introduction

This guide will show you how to replace or install dampers on the Creality CR-10S 3D printer in order to provide some noise reduction while printing. The dampeners are made of rubber material, this will separate the metal frame of the motor from contacting the metal bracket of the 3D printer, greatly reducing the vibrations that create noise.

It is important to note that this process can be replicated for all CR-10 devices with similar stepper motors.

Before You Begin

  • Ensure that there is no power flowing through the unit by disconnect the power cable.
  • Read through the guide to familiarized yourself with the process.
  • Know the location of the components. The above image shows the x-axis components in red and the y-axis components in blue.
  • Remember to be gentle with some of the hardware. Putting too much pressure turning a screw may strip it making it difficult to remove in the future.
  1. Using the 3mm Allen key, remove the (2) two 3mm Allen head screws on either side of the y-axis bracket to undo tensioner. Push forward to give the belt slack.
    • Using the 3mm Allen key, remove the (2) two 3mm Allen head screws on either side of the y-axis bracket to undo tensioner. Push forward to give the belt slack.

  2. Using the 2mm Allen key, remove the (4) four 2mm Allen head screws holding the motor and set down with the gear wheel facing up. Install the damper using (2) two of the 2mm Allen head screws. When installing the dampener onto the motor, ensure that the wider opening of the dampener is facing the motor.
    • Using the 2mm Allen key, remove the (4) four 2mm Allen head screws holding the motor and set down with the gear wheel facing up.

    • Install the damper using (2) two of the 2mm Allen head screws.

    • When installing the dampener onto the motor, ensure that the wider opening of the dampener is facing the motor.

  3. Reinstall the motor using the remaining (2) two 2mm Allen head screws by mounting the damper onto the bracket. Adjust the gear wheel by undoing the (2) two 2mm Allen head screws,  centering the wheel, and re-tightening the screws. Once the gear wheel is centered, reinstall the belt.
    • Reinstall the motor using the remaining (2) two 2mm Allen head screws by mounting the damper onto the bracket.

    • Adjust the gear wheel by undoing the (2) two 2mm Allen head screws, centering the wheel, and re-tightening the screws.

    • Once the gear wheel is centered, reinstall the belt.

  4. Tighten the belt by pulling on the tensioner bracket and tightening the (2) two 3mm Allen head screws.
    • Tighten the belt by pulling on the tensioner bracket and tightening the (2) two 3mm Allen head screws.

  5. Unscrew the 3mm Allen head bolts on the x-axis tensioner and push the bracket toward motor to create slack on the belt.
    • Unscrew the 3mm Allen head bolts on the x-axis tensioner and push the bracket toward motor to create slack on the belt.

  6. Unscrew the (4) four 2mm Allen head bolts holding the motor and sensor to the chassis. Undo the belt and remove the stepper motor from the mount.
    • Unscrew the (4) four 2mm Allen head bolts holding the motor and sensor to the chassis.

    • Undo the belt and remove the stepper motor from the mount.

  7. Install the damper onto the motor as explained in Step 2. Ensure that the gear wheel is centered similarly to Step 3 before doing the final assembly. Reinstall the motor onto the bracket by re-using (2) two of the long 2mm Allen head screws.
    • Install the damper onto the motor as explained in Step 2.

    • Ensure that the gear wheel is centered similarly to Step 3 before doing the final assembly.

    • Reinstall the motor onto the bracket by re-using (2) two of the long 2mm Allen head screws.

    • You will have to hold the sensor cover and motor in place when performing this installation.

  8. Tighten the belt by pulling on the tensioner bracket as you tighten the (2) two 3mm Allen head screws.
    • Tighten the belt by pulling on the tensioner bracket as you tighten the (2) two 3mm Allen head screws.

Conclusion

To reassemble your device, follow these instructions in reverse order.
